1647.6 MHz is your CPU's speed at idle. To see how much you've overclocked it, run a stress-testing program like Prime95 and see what speed it shows while stress testing.
Thanks so much for your quxk reply. Okay, I will do that, but also, 1647 traslates to what in Ghz? Would that be 1.647 X4? Or, how is that determined? ..So I can know what it's running at in terms of GHz?
Thanks very much! I really appreciate your help!
Hope to hear back from you ASAP.
